I'm using OSG 2.8.3, the last stable release. I'm using a Viewer with GraphicsWindowEmbedded.
On closing the window, the Viewer is destroyed, and the destructor tries to close the GraphicsContext. Inside flushAllDeletedGLObjects, flushDeletedGlPrograms is called. Inside that, there is a call to GL2Extensions::Get(). And in that, if s_extensions[contextID] is 0, it is trying to construct a new GL2Extensions object. Finally, that's calling glGetString(GL_VERSION). But by now, the graphics context is no longer valid. Should I be able to set up a Viewer or CompositeViewer such that it can be destroyed when the graphics context is not current? What about if it does not exist anymore? thanks andy _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
